NS06
NS06 is a dual-target inhibitor of STAT3 and HDAC, with a Kd of 5.82 μM for human STAT3, an IC50 of 129.1 nM for human HDAC1, an IC50 of 451.2 nM for human HDAC3, and an IC50 of 230.4 nM for human HDAC6. NS06 binds to STAT3 to inhibit its phosphorylation without altering the total STAT3 level; it inhibits the enzymatic activity of HDAC via coordination with Zn2+ at the catalytic center of HDAC1 and increases the acetylation level of histone H3. NS06 induces cell apoptosis, inhibits cancer cell migration and colony formation, and exhibits antiproliferative activity against solid tumor cells and 3D tumor spheroid models. NS06 is applicable to solid tumor-related research.

NS06 (30-60 min) potently inhibits recombinant human HDAC1 (IC50 = 129.1 nM), HDAC3 (IC50 = 451.2 nM), and HDAC6 (IC50 = 230.4 nM) in vitro, with limited activity against HDAC4 and HDAC11[1].
NS06 (0.31-10.0 μM) binds directly to recombinant human STAT3 protein with moderate affinity (KD = 5.82 μM) in vitro[1].
NS06 (5 μM; 0-150 min) shows moderate metabolic stability in rat liver microsomes, with a half-life of 48.6 min and an intrinsic clearance of 28.53 μL/min/mg microsomal protein[1].
NS06 (0.10-100 μM; 48 h) shows potent, selective antiproliferative activity against human solid-tumor cell lines (IC50 = 1.41-6.40 μM) with low cytotoxicity toward non-cancerous NCM460 cells (IC50 = 33.86 μM), resulting in favorable selectivity indices for most tumor cell lines[1].
NS06 (1 μM; 4 h) increases acetylated histone H3 levels in HCT116 and MDA-MB-231 cells, confirming functional intracellular HDAC inhibition[1].
NS06 (1 μM; 4 h) suppresses STAT3 phosphorylation in HCT116 and MDA-MB-231 cells without affecting total STAT3 protein levels[1].
NS06 (1 μM; 10 days) potently inhibits long-term colony formation in HCT116 cells[1].
NS06 (1 μM; 48 h) potently inhibits Transwell migration of HCT116 cells[1].
NS06 (1-2 μM; 29 days) inhibits 3D HCT116 tumor spheroid growth in a concentration-dependent manner[1].
NS06 (1-2 μM; 48 h) induces concentration-dependent apoptosis in HCT116 cells[1].
